NNING MACHINERY COR-YOBL'IION, A 003- CAN-FILLING MACHINE.

Application and October 22,1917. Serial no. 19am.

To all whom it may concern:

Be it known that OswALn H. HANBEN, a citizen of the United States, residing at Port Washin n, in the county of Ozaukee B and State of isconsin, has invented a certain new and useful Improvement in Can- Filling Machines, of which the following is a s ecification. 1

his invention relates to improvements in the construction and operation of can filling machines, and has particular relation to improvements in machines for automatically fillling cans with a mixture of liquidand solids such as'peas, beans, berries, and the like.

An object of the invention is to provide a can filling machine which is simple and compact in construction and efiicient in operation. Another object is to'simplify and 0 improve the construction and operation of the can filling machine disclosed in Patent No. 1,188,764, granted June 27, 1916.

Some of the more specific objects of the present invention areas follows To produce a sanitary, compact, simple can filling machine of maximum capacity and minimum power consum tion, which may be readily and safely manipulated by a single attendant.

To provide a device, which will entirely eliminate injury and waste of the substance being handled.

To provide means for automatically, accuratel and rapidly proportioning and effective y mixin the materials, and for eliminating air rom the mixture.

To provide. mechanism for quickly and accurately adjusting the proportions of the materials in the mixture, without interrupt- 40 ing the operation of the machine;

- 0 provide a machine of simplified structure which may .be readily assembled and disassembled, and in which all parts are readily accessible.

To provide a filler in which danger of injury to the cans is eliminated, and in which the cans are gradually and gently delivered to, through and from the machine To rovide'various other details of construction and operation which will reduce to a minimum the cost, and enhance to a maximum the efliciency of the machine.

A clear conception of an embodiment and of modifications of some of the features of the invention may be had by referring to the drawlngs accompanying and forming a part of this specification, in which like reference characters designate the same or similar parts in the various views.

Fig. 9 is a fragmentary enlarged sectional view of one of the mixture measuring pockets and associated elements, showing a device similar to that shown in Fig, 5 for varying the volume of the measured quantity of mixture.

The term peas as employed in the pre ent specification and claims, refers to any material or substance havin characteristics similar to those of peas. The term edge as applied to the division portion between the successive pea measuring pocket-s, should not be limited to meaning a corner, as this 1. ragmentary enlarged transat their lower ends by tie rods 39, at their niid-portions'by means of a horizontal frame element 15, and at their upper portions by means of a horizontal frame element 9, see Fl 1 to 4 inclusive. A. circular plate 8 is ed to the upper central portion of the frame element 9 and forms a support for the rotary mixture measuring element 7. The element 7 comprises spaced upper and lower discs having an annular series of seven c lindrical walls between them which form t e mixture measuring pockets 33. The rotary element 7 is provided with a central hub extending upwardly from the lower disc to a point some distance above the pockets 33, this hub bein provided with a central through here the lower extremity of which engages the upper end of the hollow main drive shaft 11. The main shaft 11 1s dr1vingly connected to the element? by means of a key34 or the like. Upon the upper disc of the element 7, \is mounted a stationary disc element 6. The stationary elements 6, 8 are provided with receses having circular taper-ed surfaces which enga the peripheries of the upper and lower iscs respectively, of the element 7, thereby centering thisele- I rnent. Th element 6 is provided with an upwardly extending bored cylindrical hub or projection which engages the cylindrical surface of the upper end of the hub of the element 7. A rotary pocket element mounted upon the element 6, and has a side projection 31 which engages adrive pin 32 secured to a lug on the element'i. An element 4 having seven downwardly depending c lindrical pocket walls cooperating with the e ement 5 and forming the walls of the pea measurin pockets 43, is rdtatably mounted upon a ange of the ring 27 which is sec ured to the stationary top frame 3.. The top frame 3 has a bore which engages the outer cylindrical surface of the upwardl extendin projection of the element 6, an has secure thereto a hopper frame 74. The hopper frame 74 is provided with a lateral pro'ection 29 which-engages vertical guides 30 ormed on th brine tank supporting arm 42, thereby positivel preventing rotation of the frame 74 and t e element 3. The pea suppl hopper 2 is supported by the frame 74 an has a discharge opening communicating with the pockets 43 through an opening formed in the disc element 3. The lorine tank 24 is mounted upon the supporting brackets or arms 41, 42 which are fixedtothe upper extremities of the side frames 17. The pin 40 secured to the upper end of the element 6 fits an opening in the element 3 thereby preventing rotation of the element 6.

The element 3, frame 74, hopper 2, pocket.

element 4 and rin 27 are simultaneously verticall adjustab e relativel to the element 5, y means a hand w eel 25 and a threaded rod 26 having" a collar engaging the element 3 and a screw threadedportion engaging a threaded opening in the upper end of the element 6; By means of this adjusting device, the volume of e a measuring pockets 43 ma be readily a tered without interrupting t e normal operation of the machine.

The lower extremity of the hollow main shaft 11 is mounted in a central bearing 22 secured to the horizontal frame element 15 The upper end of th shaft 11 engages a bore providing a bearing" in the stationary plate 8.. The bevel gear 16 is secured to the shaft 11 and rests upon the bearing 22. A cauconveying element 13 having can hooks 1'6, has a central bore which engages the shaft 11, and is drivingly connected to the gear 16 b means of a rod 36. An annular series of nnels 10 secured. to a funnel supri: 12 having central bore engaging the 11, is also rotatably connected to the bevel ear 16 by means of the rod 36. The funnel; 10 and funnel support 12 are vertiwlly adjustable relatively to'the rotating element 13, by means of one or mor set screws 35 which engage screw threaded openings in the support 12 and have heads which abut the element 13. The cans 19 are transported or urged along an upper plane surface 38 of the frame element 15, by the can hordes 76, see Figs. 1 4, and are guided in a circular path by means of a curved can guide 14. The can guide 14 has three downwardly depending supporting lugs which engage an upper surface of the frame element 15, and two or more of which are bored to fit parallel upwardly extending guiding pins 7 7 secured to the element 15. The can ide 14 is freely vertically removable from t e pins 77 in order tolaterall liberate the cans 19, such liberation being esirable when an abnormal can becomes 'arnmed between the element 13 and the gui e 14.

A power cross shaft 20 mounted in bear-- ings formed integral withthe frame ele ment 9, has a bevel pinion 18 secured thereto which meshes with the bevel gear 16. The

iic

shaft 20 has a thrust collar 37 thereon which iso drivin pulley 21, see Fig. 1 and 2. A fricface 38 of the stationary frame element 15 by means of a can feed guide 80 which automatically rights the cans and feeds them to the machine in vertical position, see Flg, 4. The delivery of the cans 19 from the guide 80 to the machine, is controllable by means of a can stop 78 which is manipulable by means of a lever 79. The cans 19 are discharged from the machine by means of a rotary can discharging wheel 82 having a series of radiating can books 83 engageable with the successive cans 19. The wheel 82 19 are urged over the plate 85 and along means of a pipe 57 communicating with a,

the adjustable guide 81 by means of the wheel 82. The brine is supplied to the tank 24 by suitable source of brine supply which is ordinarily located on an upper floor of the canning factory,'seeFig. 2. The discharge end of the pipe 57 is controlled by means of Y a float 55 which rests upon the liquid in the tank 24 and actuates a valve device 56. The tank 24 communicates through a screen '62 and a pipe 50, with a brine supply header or manifold 49. Brine cut-01f valves 59, 58, located in the pipes 57, respectively, are

operatively connected by means of a connecti0n-60 having a slotted end 63 cooperable with a pin on the control'lever 61. The brine manifold 49 communicates with brine passages 73 formed between the element 9 and the plate 8, see Figs. 3 and'5. The passages 73 communicate with supply openings 67 which penetrate the plate 8 and are communicable with the lower extremities of the mixture measuring pockets 33. Communicating with the upper portion of each of the mixture measuring pockets 33, are vertical air vent passages 51 which are formed in the element 7 and extend upwardly above the level of the liquid in the brine tank 24. The vent passages communicate with the atmosphere through the opening in the hollow shaft 11. In the device disclosed in Figs. 5, 8 and 9 the level of the liquid within the pockets 33 is determined by means of insert blocks 72. By inserting insert blocks 72 of different vertical heights as shown in Figs; 5 and 9, the volume of and the funnels 10.

. vice 56.

the confined air space at the upper ends of the pockets may'be varied, thereb varying the volume of the measured.

The up er portions of the division walls between t e successive cylindrical pea measuring pockets 43, are provided with rectilineal portions or edges which extendsubstantially radially of the axis of the main shaft 11, see *igs. 2 and 6. These edges 70 are cooperable with a rectilineal longitudinal recess formed in the oscillatory cut-ofi valve 52. The valve 52 is operable by means ofan actuating arm and a .weight 54, and is stopped innormal position by means of a valve stop 53 which cooperates with the element 3. The valve. actuating arm 75 is successively cooperable with lugs 28 formed on and projecting laterally from the rotary pocket element 4 adjacent the edges 70 thereof.

The material-in the hopper 2 is automatically and continuously agitated to prevent clogging of the hopper discharge opening, by means of an agitator 44 operable by bell cranks 46. 47 which are actuable by the lugs 28, see Figs. 2 and 7. The bell crank 46 is mounted upon a shaft 45 to an end of which the agitator 44 is also secured. The

bell crank 46 has a recessed arm cooperable with an arm of the bell crank 47. The bell crank 47 is pivotally mounted upon the element 3 by means of a pivot shaft 48, i

The stationary plate 6 is provided with an opening 69 forming means of communication between the pockets 43 and the pockets 33, see Fig. 3. The stationary plate 8 is provided with an opening 68 forming means of communication between the pockets The funnels 10 are spaced from the plate 9 and also clear the tops of the cans 19.

' During the normal operation of the machine, the operating lever 61 is thrown toward the extreme left as viewed in Fig. 2, connecting the power pulley 21 with the cross shaft 20 through the clutch 65, and rotating the main shaft 11 and associated elements through the gears 16, 18. The rotation of the gear 16 is also transmitted to the gear 86 through the gear teeth 87.causing the can discharge wheel 82 to rotate. After the lever 61 has been thrown to the left, the valves 58, 59 may be opened wide by moving the connection 60 to the extreme left, thereby causing brine to flow into the tank 24 through the valve device 56 from'the main supply tank. As the brine level in the tank 24 rises, the float 55 gradually cuts off the brine supply admitted through the valve de- The tank 24 is preferably constructed of suilicient capacity so that if the main brine supply is-interrupted. the supply to the cans 19 will not be immediately affected. The brine flows from the tank 24 quantities 0 mixture per discharge opening, the cut-ofi valve 52 is automatically actuated by means of the adjacent lug 28 engaging the valve actuating arm 75, and cooperates with the adjacent pocket edge to cut oh the pea sup" ply. without in. any way injuring the peas. After the advancing pocket edge'ZO adjacent the valve 52, has reached a predeter mined position, the arm disengages the adjacent lug 28 and the valve 52 is flipped hack to normal position by means of the weight 54. i

The advancing filled pea pockets 43 upon reaching the opening 69 in the element 6, deliver their contents into the corresponding mixture measuring pockets 33 directly be low. As these pockets 33 assume positionsv directly above the brine openings- 67, the brine enters the pockets from the manifold 49 and passages 73. The entering brine rises within the pockets 33 filling the voids be tween the peas and'forcing the air from the pockets through the vents '51 and shaft 11. The advancing pockets 33 after being filled with the mixture of peas and brine, eventually reach a position of alinement with the opening 68 in the plate 8. whereupon the contents of the pockets 33 are successively delivered into the corresponding funnels 10 directly below. The material passing through the funnels it) is delivered by gravity into the cans 19 which are successively transported over the surface 38 of the frame element 15 by mews of the can hooks 76. The spacing of the can hooks 76 is such and the can guide 14 is so disposed, that the successive cans are placed directly in vertical alinement with the funnels 10. The filled cans 19 are gradually urged along the surface 36 and are eventually delivered to the rotating can discharging wheel 82 the hooks 83 of which take the filled cans 19 away from the hooks 76 sliding them over the plate 85 and along the guide 81, and delivering them to a conveyor which leads to the capper.

it will thus be noted that each can 19 is gradually and automatically filled with an accurately measured charge of accurately proportioned mixture of brine and peas. There are no abrupt changes in the direction of travel of the cans 19, these cans being urged along the plane surface 38 and gradually curved guide 14 and delivered from the machine, without jarring or splashing their contents, thereby eliminating waste of material and permitting operation of the machine at maximum speed with resulting maximum capacity. The cans 19 engage the alon lines rat tone the funnels 10 as in the prior machines of this type, thereby eliminating danger of jamming. The can guide 14 may be quickly vertically removed from the pins 7 7 thereby laterally liberatin the cans 19 if desired, since the guide 14 is held in normal position by gravity alone. The supply of cans 19 may be quickly stopped hy manipulation of the lever 79. As the power and can feed controlling levers are located on the same side of the machine, a single attendant may readily manipulate the levers 61, 79 to control the operation of the entire. machine. The lever 61 provides means for simultaneously stopping the lorine supply and interrupting the power supply, while the slotted end 63 of the connection 66 permits application. of the power without opening the brine supply controlling valves 58, 59. With this arrangement of elements, the machinemay be run idly.

The entire machine is simple and compact in construction, the various elements being readily removable or accessible for inspec tion and cleaning. The superposed elements 3, 4, 5, 6 and 7 and the associated parts thereof, are held in normal position by gravity alone, being freely vertically removable even'when the machine is in motion. The projection 29 and guides 30 form simple means for preventing rotation of the frames 74, 3 while permitting vertical adjustment thereof. The pin 40 coacting with the stationary element 3, effectively prevents rota tion of the element 6. The pocket element 7 is driven by the main shaft 11 through the key 34 and transmits rotary motion to the \pocket elements 4, 5 through the pin 32 and projection 31, this structure providing an effective direct drive extending across the periphery of the stationary element 6. The driving pin 36 provides simple and eil'ective means for transmittingrotary motion from the gear 16 to the conveying element 13 and funnel support 12, at the same time permitting verticalv adjustment of the funnels 10 by means of the set-screws 35. The driving mechanism for the can discharging device is simplified by forming the gear teeth 87 directly upon the periphery of the main gear 16. The main shaft 11 is preferably formed of brass tubing, the gear 16 being secured thereto by means of a transverse pin or the like.

The pea measuring pockets 43 are preferably formed cylindrical in order to facilithe edges and the phase relation between .10 9

these ements when in motion, is such that the largest size of ea will not be crushed if lodged between t e elements.

By admitting the brine at the bottom of the mixture measuring pockets 33, see Fig. 5, the liquid will readily percolate through the voids between the peas and will force the air out of the pockets through the air vents 51. The pockets 33 after receiving the proper quantity of peas, are maintainedin communication with the brine supply through the openings 67, a suflicient length of time to insure admission of sufficient brine. The air vents 51 are formed in-the element 7 and are readily completely accessible for cleaning, by removal of the element 6 and the elements coacting therewith. The upper extremities of the vents 51 are open to atmosphere and are locatedsuflicient distance above high liquid level in the tank 24, to prevent overflow of brine.

The volume of the pea measuring pockets 43 may be readily varied during normal operation of the machine, by adjustment of the handwheel 25, see Fig. 1. Such adjustment of the hand-wheel raises or lowers the frame 6 and element 4 thereby changing the depth of the pockets 43. The volume of the quantities of mixture may be varied by inserting blocks 72 of difierent vertical thickness thereby varying the volume of the confined air space at the upper end of each pocket, see Fig. 5.

The, provision of alternate openings 69, 67, 68 and sealing spaces in the elements 6, 8 and the utilization of seven mixture measuring pockets 33 cooperating therewith, provides an exceedingly compact construction in which the materials are effectively admitted to and discharged from the succes sive pockets 33, and in which leakage of liquid is eliminated. The peas are admitted to the upper ends of the pockets 33 as they approach from a sealing space, through the opening 69 in the element 6 after which the advancing pockets are sealed. As the pockets advance further the brine is admitted also desirable to have the lengths ofthe openings 68, 69, of the sealing spaces, and

of the pockets 33 substantially equal, andto have the brine admission means about twice the length of each of the other openings in order to insure a full supply of brine when operating at high speed.

The peas in the hopper 2 are prevented from choking the discharge opening thereby facilitating high speed operation, by means of the automatically actuated agitator 44. This agitator is oscillated by means of the bell-cranks 46, 47 one of which engages an advancing lug 28- to swing the agitator 44 in one direction, and the other of which engages the same lug 28 to reverse the agitator motion.

The entire machine is also constructed to maintain a pleasing, symmetrical appearance, and the various elements are constructed of materials best suited to withstand the wear and tear to which they are subjected.

It should be understood that it is not desired to limit the invention to the exact details of construction and operation shown and described, for various modifications within the scope of the claims,.inay occur to a person skilled in the art.
